jWebSocket is open source and based on the Apache license so you're free to use it without charge. It works using HTML5 WebSockets and falls back on a Java client for communication for compatibility purposes. The server is also Java-based. Using the HTTP protocol for these types of communications wastes many resources and doesn't perform as good as always-open TCP connections such as HTML5 WebSockets. The server could be programmed in either Java or Java-interpreted JavaScript. The client could be programmed in just about any language.
